摘　　要：有机-无机杂化体异质结太阳电池以无机半导体纳米晶作为电子受体,共轭聚合物作为电子给体,是近年来的一个研究热点。在设计上,有机-无机杂化材料兼具有机材料的柔性、结构多样性、易加工和无机材料载流子迁移率高、稳定性好的优势,具有良好的发展前景。介绍了有机-无机杂化体异质结太阳电池的结构、工作原理,从共轭聚合物、无机半导体纳米材料以及电池制备工艺3个方面综述了近年来国内外研究现状,主要包括有机-无机杂化体异质结太阳电池中常用共轭聚合物结构、带隙,无机纳米晶种类、形貌、表面改性以及有源层厚度、形貌调控等内容。着重介绍了基于CdSe、TiO2、PbS类纳米晶的太阳电池。最后讨论了有机-无机杂化体异质结太阳电池目前存在的问题和发展方向。Organic-inorganic bulk heterojunction（ BHJ） solar cells which consist of conjugated polymers as electron donors and inorganic semiconductor nanocrystals as electron acceptors,have attracted extensive research in recent years.They combine the advantages of organic materials and the inorganic counterparts,the flexibility,design capability and easy-processing of organic materials as well as high charge mobility and good stability of inorganic ones,and have good prospects for development. In this article,we first explain the structure and general working principles of organic-inorganic BHJ solar cells and then review the recent developments of conjugated polymer,inorganic materials and device preparation process,including chemical structure and bandgaps of common polymers,morphology and surface modification of inorganic nanocrystals and control of active layer thickness and morphology. Cd Se,TiO2,Pb S nanocrystals based organic-inorganic BHJ solar cells are mainly introduced. Finally,we discuss the problems of organic-inorganic solar cells and their future developments.
